Interactive Sensory Laboratory Exercises (ISLE) is a complementary set of activities, experiments, and
illustrations that allow students to engage the concepts of Sensation & Perception by interacting with
the phenomena discussed in the book, including anatomical diagrams, visual illusions, auditory illusions,
and musical selections.

Hands-On Experience
In working through these exercises, students have the opportunity to interact and see how different
variables alter their experience. For example, students can:

• Try out Kuffler's experiment exploring center-surround receptive fields and other models of cells in the
brain, with results generated in real time.

• See what a photograph looks like to people with different forms of dichromacy, and upload their own photographs
to see what happens.

• Read about hue cancellation and then run an experiment that allows them to manipulate the stimulus and
method settings.

Anaglyph glasses
Some of the photographic figures on ISLE are anaglyphic stereo­grams, and they will require special glasses
to be seen properly. See chapter 7 for more information about stereograms. While these glasses are not
provided with the book, they are easy to make, or, if you prefer, cheap to buy, individually or in bulk.
Please note that you will need Red/Cyan anaglyph glasses. Consult
ISLE P.1 for specific information about
either making or ordering these glasses.

Assessment
You can see the results of these experiments and collect the data in an Excel-ready format that is compatible
with any statistical analysis package. In addition, there is a full set of quiz questions to be uses to
assess what students have gained from interaction with the exercises.

Flexibility
The site is designed to work on most platforms, devices and browsers, and is optimized for display on tablets
and mobile phones.
Each exercise also includes its own set of specific instructions.
